Essay

Provide an appropriate response
-A simple random sample of 15-year old boys from one city is obtained and their weights (in pounds) are listed below. Use a 0.01 significance level to test the claim that these sample weights come from a population with a mean equal to 150 lb. Assume that the standard deviation of the weights of all 15-year old boys in the city is known to be 16.4 lb. Use the traditional method of testing hypotheses. $$\begin{array} { l l l l l l l l l l l } 144 & 140 & 161 & 151 & 134 & 189 & 157 & 144 & 175 & 127 & 164\end{array}$$

Definitions:

Current Transformer

A transformer used for metering alternating current. Current transformers generally have a standard output current value of 5 A at rated primary current.

Moving Vane

A mechanical component in some measurement devices that moves in response to an external physical quantity, such as fluid flow or electrical current.

High Resistance

A characteristic of materials or components that oppose the flow of electric current, resulting in a low current for a given applied voltage.

Loading Effect

The impact on a circuit when a measurement device or an additional component is connected, altering the circuit's original behavior.
